It seems like Hailey is really embracing her married life with Justin Bieber!

TMZ reports that Hailey has already filed to trademark her new name so she can use on merchandise and stop anyone else from doing so.

Bieber and Baldwin are believed to have tied the knot back in September at a New York City courthouse, although they didn't confirm the news themselves until last month verbally to a fan and now to the world on Instagram.

Hailey and Justin have been pretty happy and excited to be husband and wife.
